Then, when something gets lost, you can track it down in an instant by its location.

As well as a map showing the position your items were last seen, there's a proximity indicator that fills with colour the nearer you get.

And, if you still can't find what you're looking for when the indicator is full with colour, the app allows you to set off a loud alert sound inside the Tile.

FIND IT: The Tile community will help you track down lost items

In our tests the Tile worked well and tracked down our keys from the side of the sofa on a number of occasions.

The tech tile concept is nothing new with other companies producing similar keyring-style alarms.

However, where Tile gets clever is if you happen to lose something whilst out and about and have no idea where you left it.

Once an object is lost, you can get other people who have joined the Tile community to help you find it.

Tile’s powerful Community Find feature has already managed to recover lost and stolen cars, motorcycles, jewellery, pets, and of course, pesky keys that get dropped in between the couch cushions or stuck in the fridge somehow.

This works as the app can anonymously update the location of a lost Tile anywhere in the world, so as a Tile member gets near a lost item an alert is automatically sent to its owner.

So with all these great features tucked inside what's the problem?

Firstly, there's the price as each Tile will set you back around £20 which is an expensive way of keeping an eye on your possessions.

This price becomes even more of an issue as the Tile only survives for around a year before its battery runs flat.

Once out of juice you have to buy a new one as you can't replace the battery.

Tile says any replacement units will be sent out at a discounted price via a service called ReTile, but you're still going to face a bill each year you own one.

APP: Tile uses your smartphone to discover its location

Our next issue with the Tile is that, in the UK, there simply aren't enough people using it yet.

Finding a lost Tile away from home and work needs other people with the app installed to help find its location.

London does have a lot of adoptors but if you lose something away from the capital you might struggle to find it.

Finally, we've had a mixed experience with our Tiles.

One has worked perfectly while the other continues to send out rouge alerts convinced that it's been lost.

FOUND: The Tile attaches to any item and can even bleep to help you find them

OUR VERDICT:

There's no doubting that the Tile is a great little tracker that has found our keys on numerous occasions.

The app works well and there's a chance you'll track down items even when you have no idea where you left them.

Sadly, the high price and one year battery life are major issues and the key to Tile's success rests on enough people joining its community – something that hasn't happened yet.

Tile's boss, Mike Farley, is confident of its future saying: “Tile reduces this time wasted and ensures valuables are in arms reach, at all times, at the touch of a button.

"We are excited about bringing the location-of-things to the UK and working with our customers to expand the Tile community across the UK and into Europe.”

He might be right, but you'll just have to decide if finding your keys is worth £20 a year.

UPDATE: Tile says it has not yet confirmed a price for its replacement trackers but they should be cheaper than the original £20 price.
